CHARLES NEBLETT, OF BELLEVUE, KENTUCKY.

BOILER-BRACE.

Application filed May 21, 1908,

To all whom it may concern:

Be it known that 1, CHARLES NEBLETT, a citizen of the United States ofAmerica, and a resident of Bellevue, in the county of Campbell and Stateof Kentucky, have invented certain new and useful Improvements inBoilerBraces, of which the following is a specification.

This invention relates to boiler-braces-of the type having spreadingfeet at one end for connection with the boiler-head and with a flat andflared opposite end for attachment to the boiler-shell and the object ofthe invention is to provide a brace that is convenient to manufacturefrom a light and thin metal but ultimately of greater strength withouttaking into its composition any more metal than heretofore used in suchdevices.

The invention consists in the provision of a laminated boiler-bracecomprising a single piece of met-a1 folded or bent over midlength andslightly canted or flared to form the shell-attaching end and with itsopposite ends turned laterally outward in opposite directions and theninward toward each other and then backward along the stem to form thefoot or head-attaching end of the device and, also, having a quartertwist made in the doubled thickness of metal intermediate the stem andshank ends of the brace, all of which will be fully hereinafterdescribed and particularly pointed out in the claim.

In the accompanying single sheet of drawings forming a part hereof,Figure 1 is a fragmentary section of one end of a steamboiler, showingone of my improved braces attached in place therein; Fig. 2, a plan view(tilted slightly downward at the left end) of the brace seen in Fig. 1,but omitting the boiler; and Fig. 3, a transverse section, taken on thedotted-line a, a, of Fig. 1, but on an increased scale and omitting theboiler, and with the device turned at a rightangle to that seen in Fig.1 but in the reverse position to that seen in Fig. 2.

In these views, 1 indicates the boiler-shell and 2 the boiler-head, bothconnected together by the usual rivets 3.

My boiler-brace, used, as customary, to properly hold the head in placein the shell, is composed of a stem A, a shank 5, a flatand flaredshell-attaching end 6 at the extremity of said shank 5 and a laterally-Specification of Letters Patent.

spreading foot 7 at the head-attaching end of said stem 4. These partsare all made up of a. single length or piece of metal, doubled overmidlength at 6 and with both limbs or members lying contiguous up to thefoot end 7, at which latter point said limbs or members are turnedlaterally from each other, then folded or bent over at 8, 8 andcontinued inwardly at 9, 9 contiguous to the first lateral extension,and then bent at 10, 10, at right-angles to the inwardly-bent portions9, 9 into inward extensions 11 that lie flatly in contact with the outerface of said two limbs or members of the stem 4. A twist 12 is mademidlength of the brace, between the stem and shank portions thereof, sothat the foot end 7 is brought into the proper relation with the narrowor shellattaching end 6 for the customary attachment of the device at anangle within the boiler. The doubling of the metal throughout the lengthof the brace provides a laminated device of great tensile strength,imparting the desired strength otherwise in the brace where necessary.

The foot-end 7 of the brace is suitably flared in relation to the stem4, taken edgewise of the latter, to suit the angle at which the brace isto be attached within the boiler, as customary.

6 6 represent rivet holes in the shell attaching end of the brace and 77 represent rivet holes in the opposite foot end 7 of the brace, bothsets being pierced through a double thickness of material and at thedesired angle to suit the position of attach ment by means of rivets 13in relation to the head and the shell of the boiler.

I claim A boiler-brace having a body portion formed from a single pieceof sheet-metal doubled over middle length, and having a partial twistintermediate its ends, a head attaching member having laterallyextending feet arranged at right angles to a part of the body portion,the laterally bent portion of the feet then being bent back uponthemselves and terminating into inwardly arranged projections, saidprojections being flush with a part of the body portion for a certaindistance of its length.
